Mechanism Category	Description	Source
Display Color Change	a mechanism that changes the display into a monochrome combination of black and white upon the detection of bystanders	[9]
Screen Brightness	a mechanism that lowers the screen brightness to make the content less visible from a distance	[9, 32, 33, 34]
Selective Visibility	a mechanism that offers a selective viewing experience by making the part the user gazes at visible while making the rest invisible to the human eye	[9, 11, 10]
Distortion	a mechanism that obfuscates the image into small pixels	[9, 35, 10, 20, 36]
Blurry	a mechanism that makes the device screen unclear, reducing the sharpness of the display	[35, 20, 37]
Replacement by Protective Text	A mechanism that replaces the content of the device screen by randomly generated unmeaningful text is activated.	[18]
Replacement by Meaningful Text	a mechanism replaces the content of the device screen with randomly generated meaningful text	[10]
Physical Tangible Component	a mechanism that relies on physical components, i.e. external to the device screen itself, not involving rendering on display - is activated, such as an LED light, which is an external part of the device but not the screen display.	[19]
Icon Overlay	an icon-like mechanism that is placed on the top of the screen to indicate bystanders	[19]
Haptic	A mechanism that relates to the sense of touch is activated. In the case of shoulder surfing, the user will be alerted through phone vibrations	[19]
Combination	A mechanism that combines multiple features into one mechanism is activated upon the detection of a shoulder surfer. For example, it adjusts font size, color scheme, and screen brightness - all of them together.	[38, 39]
